Does changing FTM clock affect UART?

I am fairly certain I know the answer, but I would appreciate confirmation before spending money to prototype.

If the PWM timer is changed for pins 21, 22, 23 on a Teensy 3.6, will it impact Serial2 communications on pins 9 and 10?
 
No, it won't.

Studying the reference manual teaches you that there is a pin multiplexer which connects pins to the different h/w building blocks. Thus, when pins 9 and 10 are muxed to the UART1 (Serial2), they can not be connected to FlexTimer0 (which handles PWM for the pins 5,6,9,10,20,21,22,23) at the same time.
